Specification of Letters Patent.

ramena-.a ivray s, 1906.

Application filed September .14, 1905i Serial No. 278,442.

The object of the present inventionis to improve the construction of dumping-cars,

more especially that shown and described in Patent No. 793,385, granted to me June 27, 1905, and to lower the tilting body of the dumping-car and arrange the same close to the truck.

A further object of the invention is to simplify and improve the construction of the ocking mechanism for securing the hinged door in its closed position and to provide a catch which will be positive and reliable in its operation and which will not cause the door to stick when the body is tilted for dumping its contents.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction wi thin the scope ofthe claims may be resorted to without departing from the spirit` or sacrificing any of the advantages of the invention.

In the drawings, Figure l1 is a perspective 'view of a dumping-car constructed in accordance with this invention, the body being tilted.' Fig. 2 is a longitudinal sectional view,

.the body being locked in a horizontal position. Fig. 3 is a detail view of the rotary Fig. 4 is a detail view taken suba' detail perspective view ofthe catch and the plate or piece which is carried by the door. ig. 6 is a detail 'horizontal sectional view of one of the front corners of the tilting body, showing the door arranged between the sides of the car.

Lik(` numerals of reference designate corresponding parts in all the figures of the draw-` ings. l

1 designates a tilting dumping-oar body provided at its front with a door 2, hinged at the top to thesid'es 3 of the body by .means of a transverse pintle--rod et, which extends entirely across the carv and which passes through suitable hinge menbers of the sides of the oar-body and the door. The front edges of the sides of the car-body are inclined, and the door, which is arranged between the sides 3 of the tilting body 1., is inclined when the car-body is arranged in a horizontal 'position, the inclination being sufficient to cause the door to close automatically and quickly, so that it will return to its closed position before the locking mechanism, hereinafter described, is operated, whereby the' automatic locking of the door will be rendered positive and reliable. The door is arranged between the sides 3 of the tilting oar-body to, prevent it whenclosed from movin laterally on the body, so thatit will not by ateral movement affect the o eration of the locking mechanism hereina ter described.

The body is provided at opposite sides with depending ears, or bearings 5, and it is pivoted by pins 6 or other suitable fastening devices to a pair of upwardly-extending arms 7 of a rotary support 8. The rotary su port 8, upon which the tilting body of the umpingcar is mounted, consists of a rectangular plate suitably secured to a movable member or ring 9 of a central' bearing or turn-table of a' Vcar-truck frame 10. The upper movable ring or member 9 is arranged upon a lower fixed ring or member 9a, on which the upper ring or member is adapted to turn when the body 1 of the car is rotated. The arms 7 are preferably formed integral with a transverse bar 11, which extends across the rotary support at the frontend ofthe same and which is secured to the said support bysuitable fastening devices. By this construction the tilting body of the dum ing-car is pivotally mounted at the front o the rotary support or turn-table and is adapted to` swing downward overthe front end of the truckframe, which is out off or beveled, as shown at 14. This will enable the tilting body of the dumping-car to be pivoted much closer to the frame of the truck than when the pivots are centrally arranged with relation to the truck, and cars of any height may be readily constructcd. The rotary su port is pierced by a central pivot or king-bo t 12, which secures the plate or -support to the truck-frame. The rotary support 1s also -provided with'a pair of rearwar ly-extending arms 13, angularly bent, as shown, and secured at their inner or front portions to the rotary support or turn- IOO tions of the arms 13 are arranged above the plane of the rotary support and have mount- A tance of the upper edge of the same.

ed on them a combined guide and'keeper 14a.

The hinged door of the dumping-car is held in its closed fposition by means of a catch 19, consisting o an arm of a longitudinal rockshaft 20, which is journaled in front and rear bearings 2l and 22 of the bottom of the car- .body. The catch 19 is arranged at an inclination and extends upwardly from the rock shaft when the door is closed. It is inclined both transversely of the body of the dumping-car and longitudinally thereof, as it extends toward one side of the ear, and also diverges upwardly from the door. The catch, which is beveled at the outer end, engages a vsubstantially triangular i'lange or lug 23 of a plate 24, which is secured to the exterior of the door and which extends upwardly from the lower edge thereof to within a short e plate depends below and is ada ted to engage the front edge of the bottom o the car-body. It forms a sto for limiting the inward movement of the oor, and the triangularflange or lug is Alocated in a plane slightly lower than the bottom of the car. The outer engaging edge 25 of the triangular flange or .lugis arranged at an angle to the door,and itis round-l ed to enable it to'slide readily over the catch when the rock-shaft is released and is free to rotate. The inward pressure on the door fa# cilitates the rotation of the rock-shaft, which is also actuated by the means hereinafter described, and the operation of ther catch is thereby rendered positive and reliable.l y

The combined guide and keeper 14a, which is disposed transversely of the rear portion of the car, is constructed substantial] the same as that shown and described in t e patent above referred to, and it presents a concave upper face and is provided at its inner end with an arm or portion 26 to form a stop and also operatin means for a wei hted arm27 of the roc k-s aft 20. When t e'dumpingbody is arranged in a horizontal position, the weighted arm of the rock-shaft isarranged in substantially a horizontal position and extends into the space between the bodyportion of the combined guide and keeper and the portion 26, and when the rear end of the tilting body is raised, the upward movement permits the weighted arm of the rock-shaft to swing downward to the inclined positio'riillustrated in Fig. 1 of the drawings. This down ward movement is rendered positive by the overhanging or projecting portion 26, which lies above the weighted or enlarged portion 2S of the arm 27. The oscillation of the arm -27 and. the consequent rotation of the rockshaft carries the catch out of engagement with the hinged door of the car and permits the same to. open. The downward movement of the weighted arm and the catch of the rock-shaft.

'gral with thearm. The arm 29 extends fromA the shaft atjthe side op osite thatat which the weighted arm and t e catch extend, and when the weighted arm and the catch swing downward the arm 29 is carried upward in engagement with the bottom of the car, whrereby the rotation of the roclcshaft is limiter between its en s in order to follow the combined guide and keeper more closely and also to increase the positive rotary movement of The locking mechanism is adapted for use -on various kinds of dumpingfcars, carts, and

analogous vehicles, and 1t may be employed The wei hted arm is bent or curved p independently of a turn-tableon cars which i have 'only a pivote'd or tilting body.

The bod is heldl against tilting by means.' substantia y the'same as those shown andf' described in the said ing referabl,v secure earody. he plate is rovided in its lower portion with a slot 34, w 'ch is engaged by a substantially L-sha ed latch 30, having ver- 'atent, the plate 33 bevtical and horizonta portions pivoted at its angle" by a pin 31 and provided at its upwardly-extending 'portion with a beveled head 32, arran ed to' engage the plate 33. The latch, whic is heldin'engagement with the plate or member 33 of a s ring 35, is mounted ina suitable casing or ousing 36.
